bool PXL_Lookup::buildOpenColorIO	(	const char *	src_color_space,
		const char *	dest_color_space,
		const char *	looks = nullptr,
		int	quality = 0
	)

Transform from one colorspace to another. quality can be 0 or 1 right now.

bool PXL_Lookup::buildOpenColorIOView	(	const char *	src_color_space,
		const char *	display_name,
		const char *	view_name,
		const char *	baked_display = nullptr,
		const char *	baked_view = nullptr,
		bool	inverse = false,
		int	quality = 0
	)

Transform from an OpenColorIO colorspace to a View, specified by a display/view pair. Always use this method to build a LUT to or from a view; do not attempt to roll your own using colorspaces and view transforms as it is not straighforward.
